Golf club with a weight member

ABSTRACT

A golf club having a weight member provided between a club and a head thereof, wherein the weight member is optionally made of materials with high density, and has a weight substantially equal to a weight of a standard head of a conventional golf club minus the weight of the head of the golf club of the invention, whereby the weight of the head is smaller than the standard head of the conventional golf club and the whole weight of the golf club is equal to the conventional golf club, so that the twisting force applying on the head of the golf club is lessened, and the stability of the golf club is improved.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a golf club having a weight member provided between a head and a club thereof so as to lessen the twisting force of the head of the golf club when a player is playing the golf.

[0003] 2. Description of Related Art

[0004] Conventionally, a golf club generally comprises a club, a head and a grip. When playing, the grip of the golf club must be held properly and the correct posture assumed to strike the ball. Then the ball is struck and travels away from the tee.

[0005] However, due to the irregular configuration, the high density and weight of the head and the long length of the club, when the head of the golf club is moving at a very high speed from above a player's head to near the player's feet, a twisting force must be applied on the head of the golf club. This force may cause the head portion of the golf club to be twisted, so that the actual striking point must be deviated from the preliminary striking point, which must cause the ball to fly in an undesired direction. It can be appreciated that the stability of the golf club is effected by the twisting force caused on the head of the golf club.

[0006] Therefore, it is an objective of the invention to provide a golf club with a weight member provided between the club and the head to reduce the twisting force applied on the head so as to improve the stability of the golf club.

SUMMARY OF THE INVENTION

[0007] The main object of the present invention is to provide a golf club having a weight member provided between a head and a club thereof, wherein the weight member is optionally made of materials with high density, and has a weight substantially equal to the weight of a standard head of a conventional golf club minus the weight of the head of the golf club of the invention, whereby the weight of the head is smaller than the standard head of the conventional golf club and the whole weight of the golf club is equal to the standard conventional golf club, the twisting force applying on the head of the golf club is thus lessened, therefore the stability of the golf club is improved.

[0008] Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0013] As shown in FIG. 1, a golf club in accordance with the invention comprises a club (10), a grip (11), a head (50), and a weight tube (20) provided between a lower end of the club (10) and the head (50). Particularly, the weight tube (20) has a weight equal to a weight of a standard head of a conventional golf club minus the weight of the head (50) of the golf club of the present invention.

[0014] With reference to FIGS. 2 to 4, the club (10) has a connecting portion (12) integrally formed at a lower end thereof, and a bore (13) defined in a center of the connecting portion (12). The head (50) has a striking face (52) formed at one end thereof, and a fixing seat (51) formed at one side of the striking face (52). The fixing seat (51) is defined with a fixing hole (511) in a center thereof. A fixing block (53) is formed in a middle position of the fixing hole (511). An aperture (54) is defined in a center of the fixing block (53).

[0015] The weight tube (20) is optionally made of materials with high density, for example, stainless steel. The weight tube (20) has a shoulder (21) integrally formed in a middle position thereof, a first end thereof defined with a first socket (23), and a second end thereof formed with a fixing tube (22) which is therein defined with a second socket (25). The connecting portion (12) is correspondingly fitted into the first socket (23) of the weight tube (20). A spindle (27) has a first end portion extended into the bore (13) of the club (10), and a second end portion extended into the first socket (23) and threadingly engaged into a first thread hole (24) defined in a bottom of the first socket (23). An adhesive material is applied between the spindle (27) and to the bore (13), and the connecting portion (12) to the first socket (23).

[0016] A connecting spindle (30) is preferably made of materials with low densities, such as PC or PBT etc., and has two opposite ends thereof respectively formed with two threads. A retaining ring (31) is integrally formed at a middle position of the connecting spindle (30). A joint portion (32) is integrally formed adjacent the retaining ring (31) and corresponds to the second socket (25) of the weight member (20).

[0017] A first end of the connecting spindle (30) is extended into the second socket (25) and threadingly engaged into a second thread hole (26) defined in a bottom of the second socket (25). The joint portion (32) is correspondingly inserted into the second socket (25). The retaining ring (31) formed with a diameter substantially equal to an external diameter of the fixing tube (22) is retained by an end face of the fixing tube (22). The adhesive material is applied between the joint portion (32) and the second socket (25).

[0018] Then the fixing tube (22) is correspondingly fitted into the fixing hole (511) of the fixing seat (51). A second end of the connecting spindle (30) is extended through the aperture (54) and threadingly engaged into a fastening member (40). The adhesive material is applied between the fixing tube (22) to the fixing hole (511), and the fastening member (40) to the fixing hole (511).

[0019] Since the weight tube (20) is equal to the weight of the standard head of the conventional golf club minus the weight of the head of the golf club of the invention, the weight of the whole golf club of the invention is equal to the weight of the conventional golf club, and the head (50) of the golf club of the invention has a weight less than the weight of the standard head of the conventional golf club. Because the twisting force caused by the weight of the head (50) is less than the twisting force caused by the weight of standard head of conventional golf club, the stability of the golf club is improved. However the player still feels a same sense of gripping the golf club of the present invention, for the weight of the golf club is same as the conventional golf club.

[0020] It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
